The Xrandr control panel applent included in Gnome 2.20 does not
support Xrandr version 1.2 which is what ships in X.org version 7.3.
To accieve your goal (without switching distros) you will need to
install the xrandr 1.2 command line utilty and use one of its
parameters to set the resolution to what you want. Once you have the
command line that does this, you can add it to your "session" in the
Gnome control panel so that it is executed every time that Gnome
starts up.
